Tej hub cov ntaub ntawv tsis yog tsuas yog muaj zog tab sis kuj heev ruaj. Lawv tiv taus khawb ntau dua iav, thiab tiv taus kub tshaj li cov hlau feem ntau. Kev siv cov ceramics tuaj yeem tiv thaiv cov khoom siv hluav taws xob zoo nyob rau hauv cov xwm txheej tsis zoo.
Nws yog tseeb vim tias ceramics yog qhov nyuaj heev uas kev ua haujlwm kuj yog qhov nyuaj heev. Txhawm rau muab ob daim hlau sib dhos ua ke, lawv yuav tsum ua kom sov siab rau qhov kub siab tshaj li 2000 ° C, uas feem ntau ua rau cov khoom siv hluav taws xob tsis zoo. Niaj hnub no, cov kws tshawb nrhiav tau tsim kho txoj kev vuam vias uas tuaj yeem taw tes-ua kom kub hnyiab ceramics los ntawm laser. Cov kev tshawb fawb ntsig txog tau luam tawm nyob rau hauv phau ntawv Kev Tshawb Fawb Science.
Cov kev qhia tshwj xeeb modulated laser yuav sov lub irradiated taw tes rau yaj hauv lub khob. Txawm li cas los, tsis zoo li lub khob uas absorbs lub teeb, ceramics muaj ib tug kev tawg ri niab ntxim rau cov teeb. Ceramic cov khoom muaj me me teeb scattering qhov nyob rau hauv cov qauv, li ntawd, lawv yuav tshwm sim opaque. Javier E. Galai, tus thawj xib fwb soj ntsuam ntawm cov neeg kho tshuab thiab aeronautical engineering nyob rau University of California, San Diego, hais tias: "Thaum koj tham txog ceramics, koj feem ntau xav seb ib tug kasfes khob los yog ib lub tais."
Rau caum xyoo dhau los, tus kws tshawb fawb ceramic Robert Cobble tawm tswv yim los kho cov txheej txheem ntau lawm kom txo qhov ntau thiab tsawg ntawm qhov hws kom ua tiav qhov pom lossis cov lus pom ntawm cov khoom siv ceramic.
Tam sim no, siv translucent ceramics thiab laser tshuab zoo xws li cov iav welding, soj ntsuam ntawm muaj peev xwm weld cylindrical tej hub ntim rau shape. Qhov sib txawv tom qab welding yog nruj heev, uas tuaj yeem tiv thaiv kom tsis txhob muaj cua thiab tswj lub xeev nqus ntawm cov khoom siv.
Qhov no muaj peev xwm ua tiav tag nrho nws cov kev siv hauv cov cheeb tsam hnyav xws li chaw. Nyob rau hauv tas li ntawd, ceramics tsis hnov mob nrog nyob ntaub so ntswg, ces lawv kuj yuav siv tau rau pob hluav taws xob implanted nyob rau hauv tib neeg lub cev.
GG quot; Qhov no yog yam tseem ceeb engineering," hais tias Shimashu Hain, ib tug ntaub ntawv paub txog ntawm Lehigh University. Txawm hais tias muaj tau yav dhau los cov kev tshawb fawb uas siv cov lasers rau yaj ceramics, qhov no yog thawj lub sij hawm uas ib tug laser twb tau muab siv rau weld tej hub blocks ua ke.
